Death is But a Door. Time is But a Window.

Egon: 
Vigo the Carpathian. 

Born 1505, died 1610.

Venkman: 
105 years old, he hung in there, didn't he?

Ray:
 He didn't die of old age, either. 

He was poisoned, 
stabbed, 
shot, 
hung, 
stretched, 
disembowled, 
drawn and quartered.

Venkman: 
Ouch.

Winston: 
Guess he wasn't too popular at the end, huh?

Egon: 
No, not exactly a man of the people. 

Also known as 
Vigo the Cruel, 
Vigo the Torturer, 
Vigo the Despised, 
and Vigo the Unholy.

Venkman: 
Wasn't he also Vigo the Butch?

Ray: 
And dig this, there was a prophecy. Just before his head died, his last words were 

"Death is but a door. 
Time is but a window. 
I'll be back."
